Message-Id: <20240905221020.2159230-1-Frank.Li@nxp.com> Date: Thu, 5 Sep 2024 18:10:19 -0400 From: Frank Li <Frank.Li@....com> To: Shawn Guo <shawnguo@...nel.org>, Sascha Hauer <s.hauer@...gutronix.de>, Pengutronix Kernel Team <kernel@...gutronix.de>, Fabio Estevam <festevam@...il.com>, Rob Herring <robh@...nel.org>, Krzysztof Kozlowski <krzk+dt@...nel.org>, Conor Dooley <conor+dt@...nel.org>, imx@...ts.linux.dev (open list:ARM/FREESCALE IMX / MXC ARM ARCHITECTURE), linux-arm-kernel@...ts.infradead.org (moderated list:ARM/FREESCALE IMX / MXC ARM ARCHITECTURE), devicetree@...r.kernel.org (open list:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS), linux-kernel@...r.kernel.org (open list) Cc: imx@...ts.linux.dev Subject: [PATCH 1/1] arm64: dts: imx93-9x9-qsb: add I3C overlay file Add an overlay file to enable I3C support on the i.MX93, replacing I2C1 with I3C. I3C is compatible with I2C, but it has not yet been enabled in arm64's defconfig. This overlay allows users to conveniently utilize I3C on the imx93-9x9-qsb platform until I3C and its driver become more mature and ready for full switch to I3C.
